* fix(bedrock): use native structured output on every Claude model whose Bedrock profiles accept it
Bedrock accepts outputConfig structured output on every reachable profile of
Claude Opus 4.7, 4.8, 5, 5.5, Sonnet 5, 5.5, Haiku 5.5, and Fable 5.1, so
json_schema now goes out natively there instead of as a forced tool, which kept
Bedrock from returning adaptive thinking. Fable 5 rejects outputConfig, so its
keys go back to the tool path. GovCloud keys keep their flags, and the drift
tests let GovCloud lag its commercial base but never lead it.
* fix(bedrock): clean Claude schemas for native structured output and keep recursive schemas on the old path
Bedrock native output rejects minimum/maximum, minItems, uniqueItems, oneOf,
additionalProperties true, and recursive or unresolved $ref, all of which the
forced tool accepted. Claude schemas on the Bedrock native paths now go through
the cleaner the Anthropic native path already uses, and a schema with a
recursive or unresolved $ref keeps the forced tool, inline, or drop path it had.
* fix(bedrock): keep older installs on the json tool with a Bedrock-only native output key
Older installs fetch the model map from main, so flipping supports_native_structured_output
moved them onto native output with their old schema handling. The new
supports_bedrock_native_structured_output key is ignored by older code. Schemas native output
cannot hold (recursive refs, open objects such as dict fields) keep the json tool on the new
key, models on the old key keep their current behavior for those shapes, and the Anthropic
API, Vertex AI, and Azure keep their current behavior.
* chore(cost-map): regenerate the model prices schema for the Bedrock native output key
* fix(bedrock): keep native output to profiles every account accepts and route schemas Bedrock rejects to the json tool
Only Opus 5.5, Sonnet 5.5, Haiku 5.5 and Fable 5.1 keep the Bedrock native output key, since
Opus 4.8 and Sonnet 5 answer 400 on some accounts and Opus 5 garbles escaped characters.
Lookaround patterns and string formats outside Bedrock's list now keep the json tool, objects
typed as a union with null are closed, and the cleaner keeps minItems of 0 or 1.
* fix(bedrock): keep Opus 5.5 and Fable 5.1 on the json tool, since native output stops their adaptive thinking
* fix(bedrock): keep shared $defs in native schemas and send refused schemas to the json tool on every native model
Native output now keeps $defs instead of inlining each use, so a submodel reused across a schema counts once against Bedrock's optional and union limits. Schemas native output cannot hold use the json tool on Converse and Invoke chat for both native keys, and minItems is only kept when it is an integer 0 or 1
* fix(bedrock): keep the json tool unless thinking is requested and bound native output schemas
The Bedrock native output key now applies only when the call asks for thinking, so calls without
thinking keep the json tool as before. Schemas past Bedrock's documented union and optional counts,
or past a grammar size estimate fitted to live probes, keep the json tool on both map keys. Open
objects keep the json tool on the Anthropic API, Vertex AI and Azure AI, where native output returned
them empty. The $ref check no longer expands $defs, so doubling definitions no longer stall the request.
* fix(bedrock): resolve root-path $defs refs so nested Pydantic models keep native output on Invoke
* test(bedrock): cover native structured output and json tool routing through the proxy
Integration cells drive the proxy against a scripted Bedrock peer that enforces Bedrock's structured output schema rules, covering thinking with native output on Converse, Converse streaming, Invoke, /v1/responses and /v1/messages, the deployment opt-in, Fable 5, schema cleaning on every native entry, open objects, and malformed schemas. Vertex, Anthropic and Azure AI cells cover open objects on native-capable models and the cleaner's minItems and nullable object handling. The unit table now covers reasoning_effort none and disabled thinking
* fix(bedrock): keep native output for numeric formats and wide old-key schemas, and keep thinking in json mode
Check string formats only on nodes that can be strings, apply the 64-field cap only to the Bedrock-only key, carry thinking blocks into the json mode message, and send malformed json tool schemas as object schemas.
* fix(anthropic): keep native output for dict fields unless the json tool can be forced
* fix(anthropic): keep native output for dict fields when the caller sends tools
* test(bedrock): close the dangerous-tool-use test schema, since Bedrock native output requires closed objects
* test(anthropic): cover forced and unforced open-object routing, json mode thinking, numeric formats and wide schemas
Add proxy cells for open-object schemas that keep native output when the json tool cannot be forced (a model that refuses forced tools on the Anthropic API and Vertex AI, thinking, caller tools), for the thinking block a json mode answer keeps on Vertex AI and Bedrock Invoke, and for integer and number formats and 65-field schemas on each Bedrock map key. Point the forced open-object cells at the Anthropic API and Azure AI only, since no Vertex AI model in the cost map takes both native output and a forced tool
* fix(bedrock): keep the native output opt-in on the deployment that sets it, and route effort none open objects to native output
* test(bedrock): cover deployment-scoped native output opt-in, register_model and effort none open objects
